I was thinking of adding the supported environment variables to the BSP once these MRs are merged. The only place I have provided a complete list is in the [RTEMS Support Planning](https://github.com/epics-base/epics-base/discussions/851#discussioncomment-16848778) issue Andrew created.
In terms of what environment variables we support there is no LibBSD documentation and adding that to add this seciton is a large piece of work that is out of scope for this change.
